Problems solved by technology

[0005] To sum up, there is no way to adjust the surface state of the core-spun yarn after it is formed in the prior art. For the adjustment of the appearance state of the core-spun yarn composed of high-elastic core yarn and low-elastic outer covering yarn, it is still necessary to seek new solutions

Embodiment 1

[0049] This embodiment provides a core-spun yarn leveling device, and the structural diagram of the device is as follows: figure 1 As shown, it includes sequentially connected yarn unwinding assembly, first roller 3, second roller 4, third roller 5 and yarn winding assembly.

[0050] The yarn unwinding assembly sequentially includes the yarn bobbin 1 to be adjusted and the first yarn guide ring 2; the centerlines of the yarn bobbin 1 to be adjusted and the first yarn guide ring 2 are located on the same vertical line; The distance between the upper end of the yarn bobbin 1 and the first yarn guide ring 2 is twice the maximum diameter of the upper end of the yarn bobbin 1 to be adjusted.

[0051] The first roller 3 , the second roller 4 and the third roller 3 independently include upper rollers and lower rollers; the lower rollers are actively driven, and the upper rollers are passively driven.

[0052] The linear velocity of the second roller 4 is greater than the linear velo...

Embodiment 2

[0055] This embodiment provides a core-spun yarn leveling device, which includes a yarn unwinding assembly, a first roller 3, a second roller 4, a third roller 5 and a yarn winding assembly connected in sequence.

[0056] The yarn unwinding assembly sequentially includes the yarn bobbin 1 to be adjusted and the first yarn guide ring 2; the centerlines of the yarn bobbin 1 to be adjusted and the first yarn guide ring 2 are located on the same vertical line; The distance between the upper end of the yarn bobbin 1 and the first yarn guide ring 2 is 1.5 times the maximum diameter of the upper end of the yarn bobbin 1 to be adjusted.

[0057] The first roller 3 , the second roller 4 and the third roller 3 independently include upper rollers and lower rollers; the lower rollers are actively driven, and the upper rollers are driven passively.

[0058] The linear velocity of the second roller 4 is greater than the linear velocity of the first roller 3 and the third roller 5, and the l...

Abstract

The invention provides a core-spun yarn homogenizing device and method, wherein the device comprises a yarn unwinding assembly, a first roller, a second roller, a third roller and a yarn winding assembly which are sequentially connected; the method comprises the steps: pulling out a core-spun yarn to be adjusted after the yarn is unwound by the first roller, then drawing by the second roller, andthen winding the yarn after the yarn is retracted by the third roller to obtain the adjusted core-spun yarn. According to the device, the core-spun yarn after being formed is drawn and retracted again, the surface state of the core-spun yarn is adjusted, bulges or knots formed on the surface of the outer-spun yarn due to the elastic difference of an inner core yarn and a covering yarn can be uniformly distributed, the quality and appearance of the core-spun yarn are fully improved, and the device is particularly suitable for a core-spun yarn composed of a high-elasticity core yarn and a low-elasticity covering yarn; the device is simple in structure, simple and convenient to operate and good in effect of adjusting the appearance of a core-spun yarn.

Description

technical field [0001] The invention belongs to the technical field of yarn weaving, and relates to a core-spun yarn leveling device and method. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a composite yarn composed of two or more fibers. The yarn of the core material is called the outer yarn. Among them, the initial core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. At present, there are many types of core-spun yarns, which can be divided into low and low-grade core-spun yarns according to their elasticity. Elastic core-spun yarn and high-elastic core-spun yarn, the former refers to the internal core material using fibers with less elasticity, and the final product formed has less elasticity, and the latter refers to the internal core material fibers using high elastic fibers , Outsourcing fibers generally use low-elastic fibers, which a...
